CRUTCH.

SPECIFICATION forming part of Letters Patent No. 265,144, datedSeptember 26, 1882.

- Application filed June 8, 18 82. (No model.)

To all whom it may concern Be it known that I, FRANK D. RANDALL, acitizen of the United States, residing at Waupaca, in the county ofWaupaca, in the State of Wisconsin, have invented new and usefulImprovements in Grutches,of which the following is a specification.

This invention relates to that class ofcrutches having alongitudinalspur-rod for ice-creeping purposes adapted to be adjusted to protrudelrom the base'or leg of the crutch and to be retracted at pleasure; andit consists, among other things, in the means hereinafter describedwhereby the rod is held in its outer or in its retracted position.

This invention is illustrated in the accompanying drawings in whichFigure l represents a side view, partly in section. Fig. 2 is alongitudinal section. Fig. 3 is a cross-section on the line or 00,Fig. 1. I

Similar letters indicate corresponding parts.

The letter A designates the bows of the crutch, meeting at the lowerends so as to form a leg, B, and having the usual shoulder-piece, C, atthe top, also the usual intermediate handheld, D.

The letter E denotes the spur-rod, which ex- 7 tends through the leg B,and to the upper end of which is fixed a cross-piece, F, having studs Gat its opposite ends. 7

To the inner sides or surfaces of the bows A, respectively, is secured aplate, H, one edge of which is provided with notches 2', two in number,adapted to receive the studs G of the cross piece. The notch-plates Hare situated directly opposite to each other and are so arrangedrelatively to the length of the spur-rod E that when the cross-piece Fis adjusted, by

one or the other direction. A stop, 1), serves to regulate thelongitudinal motion of the spurrod. The upper portion of the spur-rod Eis guided by means of eyes j, forming part of a filling-frame, K,combined with the crutchbows. This filling frame is located on the lowerpart of the crotch, and a secondary or supplementary filling-frame, L,is arranged be tween the crutch-bows on the upper part of the article.The function of these frames K 11 is both to ornament and strengthen thecrutch, the upper frame, L, serving also to secure the shoulder-piece C.

At the lower end of the crutch-leg is a ferrule, a, of cup shape,containing a pad, 0, of india-rubber, which forms the bearing of thecrutch when the spur-rod is retracted.

The hand-hold D is fastened by means of a bolt, 1", passing through itand engaging with side plates, s, on the crutch-bows.

The stopp coacts with the eyes j of the filling-frame, and by meansthereof the end studs of the cross-pieces F are brought opposite to thenotches i of the notch-plates when the spurrod is moved in or outward.

What I. claim as new, and desire to secure by Letters Patent, is-- 1.The combination, substantially as hereinbefore set forth, ofthenotch-plates arranged opposite to each other with their notches openingin opposite directions, with the spur-rod arranged to rotate, andprovided with a crosspiece having end studs adapted to engage theplate-notches, for the purpose specified.

2. The combination, substantially as hereinbefore set forth, with thespur-rod, of the tilling-t'rame provided with eyes forming guides forsuch rod, as specified.

3. The combination, substantially as hereinbefore described, with thespur-rod, of the tilling-frame, provided with eyes forming guides forsuch rod, and the stop.

In testimony whereof I havehereunto set my hand and seal in the presenceof two subscribing witnesses.
